WILLIAM ,ADAMSON. PHILADELPHIA, PENNSYLVANIA Letters Patent No. 65,787, dated June 18, I867.

IMPROVEMENT IN THE MANUFACTURE OF GLUE.

To ALL WHOM IT'MAY CONCERN:

Be known that I, IYILLIAM ADAMSGX, of Philadelphia, Pennsylrania, have invented an improved- Glue; and I do hereby declare the following to he a full, clear, and exact description of the same.

My invention consists of ordinary glue (or size prior toits conversion into glue) combined with bihornte of sod-.1. or borax, substantially as described hereafter, the product being a tenacious glue, partially bleached, and not so liable to fermeqtation and rotting as ordinary glue. v

,In orderito enable others familiar with processes of this class to make my invention, I will now proceed to deserihe the mode ol r producing the sauie.

Myiuvcntion may be carried into efl'ect either by inixingdissolved glue with the biborate of soda, or by l'mxin the latter with size prior to the conversion of the some into glue by theLnrdinm-yprocess of" drying or dosiccat' l I e I a 0 n i mg, or by the aerat ng or carbenzttmg' process described in a separate applicat on for a patent which I have this day inade. The product may be obtained by dissolving about twenty pounds of b'rboratc of soda in as much water ms will be necessary to effect athorough solution, and mixing the latter with about one thousand pounds of melted glue or size. The proportiouof the borax to the glue or size, however, will depend upon the condition of the latter, which condition can be readily understood and ascertained by those familiar with the manufacture Of glue. 7

The solution of biborate of-soda may-he applied in about the above proportions to size, prior to the con- 'version of the samcvinto glue by the ordinary drying or desic'catiug' procns but I prcfer to apply the solution to the size immediately after aerating or treating the same with gas, as I havezdesrribed in a separate application for a patent.

I claim as 'my inventign, and desire to secure by Letters I:rtenl The combination, substantially-as described, of -glue or size with biborute of soda,"for the purpose specified.

In testimony whereofI have signed my name to this specification in'the presence oftwo subscribing witnesses...
